Sex differences in the early life stages of the salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae)
(Journal article; Peer reviewed, 2022)Salmon lice are ectoparasites on salmonids and feed on blood, mucus, and skin from their hosts. This causes high annual costs for treatment and control for the aquaculture industry. Salmon lice have a life cycle consisting ... -
Sex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies
(Peer reviewed; Journal article, 2012-06-18)Background: In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetically ... -
Sexual dimorphism of drumming muscles in European hake (Merluccius merluccius)
(Peer reviewed; Journal article, 2010)Dissections of mature and non-mature European hake males and females (N = 142) collected in waters off the western coast of Norway and in the Bay of Biscay (France) in 2004–2006 demonstrate for the first time that this ... -
Sexual size dimorphism of bark and ambrosia beetles
(Master thesis, 2016-06-01)Size is a defining feature of an animal and is a result of counteracting forces of selection, and studying size and SSD can reveal what drives selection of body size in a given direction. Scolytinae and Platypodinae are ... -
sFDvent: A global trait database for deep‐sea hydrothermal‐vent fauna
(Peer reviewed; Journal article, 2019)Motivation: Traits are increasingly being used to quantify global biodiversity patterns, with trait databases growing in size and number, across diverse taxa. Despite growing interest in a trait‐based approach to the ... -
Shallow and deep groundwater moderate methane dynamics in a high Arctic glacial catchment
(Journal article; Peer reviewed, 2024)Glacial groundwater can mobilize deep-seated methane from beneath glaciers and permafrost in the Arctic, leading to atmospheric emissions of this greenhouse gas. We present a temporal, hydro-chemical dataset of methane-rich ... -
The Shallow-water Macro Echinoderm Fauna of Nha Trang Bay (Vietnam): Status at the Onset of Protection of Habitats
(Master thesis, 2006-05)Hon Mun Marine Protected Area, in Nha Trang Bay (South Central Vietnam) was established in 2002. In the first period after protection had been initiated, a baseline survey on the shallow-water macro echinoderm fauna was ... -
Shedding Light on Fish Otolith Biomineralization Using a Bioenergetic Approach
(Peer reviewed; Journal article, 2011-11-14)Otoliths are biocalcified bodies connected to the sensory system in the inner ears of fish. Their layered, biorhythm-following formation provides individual records of the age, the individual history and the natural ... -
Shelter seeking and competitive behavior in hatchery reared juvenile European lobster (Homarus gammarus) exposed to predator odors
(Master thesis, 2012-07-01)Releases of hatchery reared juvenile European lobster have been performed throughout Europe since the 19th century. However, poor survival in the wild reduces the success of both stock enhancement programs and large-scale ... -
Shifts in soil prokaryotic communities of boreal and alpine semi-natural grasslands along temperature and precipitation gradients: An investigation into the effects of graminoid removal
(Master thesis, 2018-06-27)Biotic interactions are important drivers of ecological responses to climate change. By studying the effects of graminoid removal on forb populations along temperature and precipitation gradients, Olsen et al. (2016) found ... -
“Show me how to use a microscope” – The development and evaluation of certification as direct assessment of practical lab skills
(Journal article; Peer reviewed, 2023)Practical lab skills are rarely directly assessed. To improve constructive alignment between the described learning outcomes of practical skills and assessment, we developed and tested a certification procedure for microscopy ... -
Similarity in Shape Dictates Signature Intrinsic Dynamics Despite No Functional Conservation in TIM Barrel Enzymes
(Peer reviewed; Journal article, 2016-03-25)The conservation of the intrinsic dynamics of proteins emerges as we attempt to understand the relationship between sequence, structure and functional conservation. We characterise the conservation of such dynamics in a ... -
A simple adjustment to test reliability of bacterivory rates derived from the dilution method
(Peer reviewed; Journal article, 2016-02)Quantification of grazing losses of marine heterotrophic bacteria is critical for understanding nutrient and carbon pathways in aquatic systems. The dilution method is a commonly used experimental approach for quantifying ... -
Simple models combining competition, defence and resource availability have broad implications in pelagic microbial food webs
(Peer reviewed; Journal article, 2018-09)In food webs, interactions between competition and defence control the partitioning of limiting resources. As a result, simple models of these interactions contain links between biogeochemistry, diversity, food web structure ... -
Simultaneous Assessment of Soil Microbial Community Structure and Function through Analysis of the Meta-Transcriptome
(Peer reviewed; Journal article, 2008-06-25)Background: Soil ecosystems harbor the most complex prokaryotic and eukaryotic microbial communities on Earth. Experimental approaches studying these systems usually focus on either the soil community’s taxonomic structure ... -
Single PFAS and PFAS mixtures affect nuclear receptor- and oxidative stress-related pathways in precision-cut liver slices of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2022)The aim of the present study was to investigate effects of per- and polyfluoroalkyl substances (PFAS), both single compounds and a mixture of these, using precision-cut liver slices (PCLS) from Atlantic cod (Gadus morhua). ... -
Site- and horizon-specific patterns of microbial community structure and enzyme activities in permafrost-affected soils of Greenland
(Peer reviewed; Journal article, 2014-10-16)Permafrost-affected soils in the Northern latitudes store huge amounts of organic carbon (OC) that is prone to microbial degradation and subsequent release of greenhouse gasses to the atmosphere. In Greenland, the consequences ... -
SIX3 and SIX6 interact with GEMININ via C-terminal regions
(Peer reviewed; Journal article, 2019-12)The histoarchitecture and function of eye and forebrain depend on a well-controlled balance between cell proliferation and differentiation. For example, the binding of the cell cycle regulator GEMININ to CDT1, which is a ... -
